REGISTERING AND NUMBERING DEVICE.

SPECIFICATION forming part of Letters Patent No. 375,804, dated January 3, 1888.

Serial No.2l7,fi20. (No model.)

To all whom, it may concern.-

Be it known that 1, CHARLES H. DAVIDS, a citizen of the United States, and residing at the city of Brooklyn, county of Kings, and State of New York, haveinvented certain new and useful improvements in devices for automatically indicating, registering, numbering, or counting persons, weights, measures, movements, periods of time, &c.such devices, in fact, as are commonly known as and designated registers and numbering-machines of which the following is a specification.

My invention relates, more particularly, to that class of such devices in which the num bers or letters used for indications are placed on the peripheries of concentric wheels.

In devices of this class as "hitherto constructed one or both of. two objectionable fea' tures are foundviz., either a certain amount ofspace between the numbering-wheels is used to admit and contain certain parts of the operating mechanism, thus separating the numbcrwheels and the figures carried by them to a greater extent than is desirable or would otherwise be required; or, if the mechanism is of such a nature as to admitthe closejuxtaposition of the number-wheels, the use of springs and other unreliable and non-positive devices is deemed necessary.

My invention consists of simple trains of positive mechanism so arranged as to be number-wheels, thus allowing a close juxtaposition of said wheels and assuring a positive certainty of their movements, as hereinafter In the drawings, Figure 1 is a longitudinal section through the center of the device at the line av 00, Figs. 2, 4, and 5, each part, except the spindle 0, being shown in section through its center. Fig. 2 is an end elevation of the 3 and a portion of a number-wheel 6, both being shown in their relative positions when the stop 3 is at rest. Fig. 4 is a side elevation of a number-wheel 6, an internal gear-wheel segment 4, and a stop 3, the latter being in position as of a halfcompleted movement. Fig. 5 is a side elevation of a number-wheel 6, the spindle O, a pinion 2, and a section of the grooved stud A through the line .22, Figs.

1 and 13. Fig. 6 is a side elevation, and Fig.

7 is a front elevation, of a pinion 2. Fig. 8 is a side elevation, and Fig. 9 is a front elevation, ofa stop 3. of an internal gear-wheel segment 4. Fig. 11 is a front elevation, and Fig. 12 is a side elevation, of a form of the stop 3 preferable for use in connection with wheels having ten digits or numbers. Fig. 13 is a side elevation, and Fig. 14 an end elevation, of the grooved stud A.

On agrooved stud, A, rotate, preferably by intermittent partial revolutions, several numberwheels, 6 6 6 6 6 6, one for each figure in the highest number which the device may be required to register or record. the grooved stud A are two collars, B B,which serve as supports for the spindle O. On the spindle O rotate the pinions 2 2 2 2 2 and stops 3 3 3 3 3, each of the latter being so secured to a pinion that it is practically a part thereof. The pinions 2 2 mesh with internal gear-wheel segments, 4 4 4 4 4, and with internal gearwheels, 5 5 5 5 5, each segment4 being secured upon one side of the web 7 ofanumber-wheel 6, each gear-wheel 5 being secured upon the opposite side of one of said webs, except as hereinafter mentioned respecting the first and last wheels of each series. In the web 7 of each wheel 6, except the last in each series, is formed a recess, 8, which admits in turn each arm of a stop 3, which is formed with several sides, preferably three in number, and is in shape substantially as shown in the drawings. Each stop 3 is placed, preferably, directly within the circumference of the web 7 of a wheel 6. The first wheel in each series requires no gear-wheel, and the last wheel in each series needs no recess in its web and requires no stop 3 nor segment 4.

The operation of the device, considered as adapted to decimal numbers, each wheel carrying the figures from O to 9, inclusive, is

rotated by suitable mechanism, presents at the point of inspection or impression the several figures named until the figure 9 has been shown orimpressed, when further rotation of the unit-wheel causes the segment 4 attached thereto to engage with and partially rotate the pinion 2, and by means of the latter and a gear-wheel 5 to partially rotate the next numher-wheel 6,which may be called the decimalwheel, a sufficient distance to bring the next Fig. 10 is a front elevation v Secured upon as follows, viz: The first or unit wheel, being i succeeding number or figure to the point of inspection or impression, as the case may be, while during such partial rotation of the decimal-wheel 6 the recess 8 in the web 7 of the unit-wheel 6 admits and receives the arm or radially largest part of the stop 8. This motion of the decimalwheel 6 having been finished, it comes to rest and cannot again be rotated until the recess 8 in the web 7 of the unit-wheel 6 is again in position to admit an arm of the stop 3. Any number of wheels may be operated as-described, each by the next preceding wheel.

A spur-pinion, Z, or other device may be attached to the spindle O, to be used for the purpose of communicating with an alarm-bell or other signal (not shown in the drawings) when a certain number has been counted by the device. In such acase the spindle (1 must be caused to revolve by being connected with one of the pinions 2.

I claim as new and as my invention- 1. A polygonal rotating stop, in combination with a rotating indicator-wheel having an internal circular face in its web, said face having a recess so arranged that at each rotation of said wheel the several angles of said stop consecutively engage said recess, permitting partial rotation of said stop and consequent operation of mechanism connected therewith, all combined with mechanism operating said stop, substantially as herein shown and described.

2. An indicator-wheel carrying a toothed internal gear segment which intermittingly meshes with and operates a spur-pinion, the latter meshing with and operating an internal gear-wheel attached to and pivoted with a second indicator-wheel, both of said indicatorwheels being pivoted concentrically, all combined substantially as herein shown and described.

3. An indicator-wheel carrying a toothed internal gear-segment which intermittingly meshes with and operates a spur-pinion which is attached to and pivoted with a polygonal rotating stop, the several sides of which consecutively engage with an internal circular face in a rotating indicator-wheel, said face having a recess so arranged that at each rotation of said wheel said recess admits an angle of said stop synchronously with the operation of said spur pinion, all combined with each other and with mechanism operated by said spur-pinion, substantially as herein shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 25th day ofOctobcr, 1886.
